My Projects

Here are some of my recent projects showcasing my skills in backend, AI, and bot development.

Projects are laid out like browser tabs: AI, fintech, crypto, data processing, and Telegram. The goal is not a glossy gallery, but quick clarity about domain, scale, and stack.

Project size is estimated as the amount of work a solo freelancer can do. 'Big' here is not equivalent to 'Enterprise'. 4 / 12 items Request consultation

Edit slide

Slide 01

PM3

Open project

Lightweight Rust process manager focused on open-source workflows, with PM2-compatible commands, built-in log rotation, and a localhost dashboard for live CPU and RAM monitoring.

Deck note

Website-highlighted focus: small footprint, PM2 migration path, real-time monitoring, and built-in log control.

Speaker notes

pm3.tech
  • Site positions PM3 as a lightweight Rust-based process manager for the open-source community.
  • Meta description highlights roughly 70% PM2 compatibility, which reduces migration friction for existing PM2 users.
  • The product pitch emphasizes a bundle size under 10 MB instead of a heavier runtime footprint.
  • Monitoring is part of the core pitch through a localhost dashboard with live CPU and RAM visibility.
  • Built-in log rotation keeps routine process supervision inside the same toolchain.
